"Since a wise government rounded up the shifty-eyed japs..." Yes, lots of the anti-japanese racism prevalent during the war is in this serial. But if you can get by that, it's an exciting, workmanlike serial, made on a shoestring. Not a great one like the Captain Marvel serial (which I think is still in the Archive), but still fun to watch.
Trivia: This serial introduced the Batcave (called "Bat's Cave") and a skinny Alfred (he'd been portly in the comics), which were quickly adopted by DC comics and have stuck ever since.
